For sale is this set of American College of Dentists cuff links and tie tack. All three pieces have the great enamel tops and measure 5/8" diameter. The links appear to have black enamel, but that is simply a reflection. The tie tack is 10k solid gold and without the clasp, it weighs 2.4 grams. The links weigh 7.7 grams and truly look like solid gold (I tested them....twice), they are gold filled. Perfect condition, dating to the 1960's. The dentist who owned these graduated in 1955.
